Correct answer & explanation
✓
Helm values override in Application manifest
ArgoCD supports 'Helm parameters' or 'Kustomize vars', but specifically for dynamic external values, the 'argocd-vault-plugin' or similar sidecar approaches are common, but using 'Application parameters' is the core supported way to override Helm values.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Helm values override in Application manifest
Why this is correct
Values can be injected via the 'helm.parameters' field in the Application spec.
- ✗
Secret injection controller
Why it's wrong here
Not a native ArgoCD feature.
- ✗
Resource hooks
Why it's wrong here
Hooks run during sync, they don't modify the manifest parameters.
- ✗
Git commit override
Why it's wrong here
Committing changes defeats the purpose of dynamic injection.
